Process for preparing a hydrocarbon active solid to be used in the polymerisation of olefines, and process for synthesising an olefinic polymer or copolymer using said hydrocarbon active solid as a catalyst
Process for the preparation of an active solid hydrocarbon which can be used to polymerize olefines. This process comprises forming a pulverulent composition by mixing a transition metal component, a porous organic or inorganic solid support and an organometallic compound of the organo-Al, organo-Mg or organo-Zn type, and polymerizing a controlled amount of one or more C2 to C12 olefines in the gas phase in contact with the pulverulent composition with a specific hourly conversion of the olefines to produce the active solid hydrocarbon. The above active solid hydrocarbon can be used, by itself or together with an organometallic cocatalyst, as a catalytic system for polymerization of olefines, in particular in the gas phase.
